The Smart Contracts Tester library is a small Python library that can be used to run any function defined in a Smart Contract. It is designed to be used for unit testing of Smart Contracts.

It provides a similar environment to the one that a Smart Contract will run in once executed in Vault. It also provides a series of mock objects that can be used to define the behaviour of the Vault API a Smart Contract uses.

There are two aspects to the library. Running functions and the types.
